Waaaahhhhh! John, Did you ever figure out how to sex those Macmasteri? I lost a bunch and have only a few left. The dominant male is quite obvious at 1 inch. The rest are just over .25 inches The others could probably benefit if I removed him to another tank. I just have no other tank to put them in as they grow out except for the pike tanks...
